For all ensemble models, the mean+spread variables are now calculated. This enables user to get the ensemble mean+spread directly, instead of downloading historical forecasts.

I need a duplicate of the Ensemble API docs with

• Title: Ensemble Mean API
• Url /en/docs/ensemble-mean-api (Do not add it to the navigation yet)
• Same variables, BUT each hourly variable has a mean + spread. Exactly like the check boxes for "Mean" and "Anomaly" in the seasonal forecast API. The "Mean" variable remains the same name e.g. "temperature_2m", but the spread variable is called "temperature_2m_spread"
• Daily variables also have "Mean" and "Anomaly". E.g. "Maximum Temperature (2 m) ☐ Mean ☐ Spread". The API does not yet support daily spread variables (e.g. temperature_2m_max_spread), but I will implement this soon.
• The models selection is the same, but they have different names. Additionally the domain "ncep_hgefs025_ensemble_mean" is available, which does not exist in the current Ensemble API. The list of variables however is the same.
• The API call weight calculation is just 1 per variable, instead multiplied by each individual members (~50)
• Ensemble means+spread will be archived and available for a longer period of time
